The ideal combo of weight, durability, comfort, and accessibility; purpose-built for thru-hiking
Co-designed with The Real Hiking Viking, a professional hike-really-long-distances-really-quickly-er, the ZERK 40 was born out of a need for an ultralight pack that can withstand the thousands of miles per year that he already covers. Mountainsmith wanted to make sure that this pack would allow him to go farther, to hike longer, and to work more efficiently on the trail. Over the course of 2 years of development, the ZERK 40 went through 4 iterations and over 5,000 miles of testing on the Wind River High Route, the Colorado Trail, the Tetons, and more.
